MACHINE FOR RUBBING NARROW FABRICS'.4

Specification of Letters Patent.

Patented July 23, 1907.

Application filed pril 22, 1907. Serial No. 369,653.

To all whom fit may concern:

Be it known that I, HENRI SIMoNIN, a citizen of the Republic of Switzerland, residing at Zrich, Switzerland, have invented certain new and useful Improvements in Machines for Rubbing Narrow Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

The subject of my invention is a machine for rubbing tape, ribbon and other narrow fabrics by means of knives, for the purpose of imparting to them a uniform appearance.

The accompanying drawings illustrate one form of construction of the invention.

Figure l is a front elevation, Fig. 2 a plan, and Fig. 3 an end elevation of the machine. Fig. 4 is a section on the line A-B of Fig. l. Fig. 5 is a front elevation-` Fig. 6 a side elevation, and Fig. 7 a plan, all drawn to a larger scale, of a portion of one of the bars with presser-feet for holding the fabrics. Fig. 8 is a detail view showing to a larger scale the construction of the parts carrying the presser-foot bars. .Fig 9, l0 and ll are views illustrating the working of the machine.

l are the standards of the machine framing, and between them is the table 2, having a pneumatic cushion 2%, over which the fabrics 3 to be rubbed travel transversely to the longitudinal axis of the machine.

5 and 6 are two horizontal bars, which slide transversely of the fabrics and are mounted on supports 4, which reciprocate vertically on guides on the standards l. The underside of the slides 5, 6 are furnished above the fabrics with knife-holders, in which are secured the knives 7 8, the knives of the one slide being inclined toward the one end of the machine and the knives of the next slide toward the other end of the machine. The slides are actuated from a shaft 9: the transverse motion being imparted with the aid of connecting-rods l0 jointed to levers ll, whose top ends are linked to the slides 5, 6 by means of rods l2, while the up and down motion is imparted to the slides by means of rods 13 pivoted to the supports 4 and actuated by eccentrics l5 mounted on a shaft 14. Between the slides 5, 6 horizontal bars 16 are provided, set on edge; and to these bars there are adjustably secured feet 17 (Figs. 5, 6 & 7) located above the fabrics. The various bars 16 are connected by carriers 18, ruiming horizontally at right angles to the bars 16. These carriers 18 are connected to the supports 14 and held down by means of springs (Fig. 8).

The operation of the machine will be understood from the following. In Fig. l the machine is shown with the knives lying on the fabrics, ready to commence rubbing. The slide 5 is in its extreme righthand position, and the slide 6 in its extreme left-halnd position. lf, now, the shaft 14 rotates in the direction of the arrow, the slide 5 will travel toward the left and the slide 6 toward the right, whereby the knives carried by the slide 5 will rub the tapes from right to left, while the other knives will operate in the reverse hdirection. This rubbing imparts a uniform appearance and gloss to the fabrics and lays any irregular warpthreads in regular position. When the slides have reached the position shown in Fig. 9, they will be lifted by the eccentric rods 13 into the position shown in Fig. l0, from which they will move into the position shown in Fig. ll. From this latter position the slides return to the position shown in Fig. l, whereupon the rubbing commences anew. The bars 16 rise simultaneously with the ascent of the slides, whereby the fabrics, hitherto pressed down upon the cushion 2f* by the feet 17, are released. The fabrics are then fed forward by a suitable device (not shown in the drawings) through such distance that those parts of the fabrics which have hitherto been lying below the feet are now rubbed by the knives. Thereupon the fabrics are fed forward through a like distance, so that fresh positions of the fabrics lie below the knives, whereupon the rubbing action is repeated, and so on, as above described.

Instead of the fabrics being held at the edges by the feet, the latter may be so located on the bars 16 that they hold the fabrics more or less centrally, as shown by the broken lines in Fig. '7. In the former ease the central portion of the fabrics is rubbed twice, in the latter case only once.

The amount of friction can be regulated by altering the pressure in the cushion.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is:

1. In a machine for rubbing narrow fabrics, in combination, a table over which the fabrics are fed, means for temporarily holding a plurality of fabrics upon the table simultaneously, knives located above the fabrics, and means for sliding the knives `across the fabrics, lifting them and returning them to their initial position, substantially as described.

2. In a machine for rubbing narrow fabrics, in combination, a table over which the fabrics are fed, vertically reciprocating bars located above and transversely of the fabrics anzl'presenting presser-feet for temporarily holdingfa plurality of fabrics upon the table simultaneously, knives located above the fabrics, and means for sliding the knives across the fabrics, lifting them and returning them to their initial position, substantially as described.

3. In a machine for rubbing narrow fabrics, in combination, a table over which the fabrics are fed, knife-bars, and bars presenting presser feet -for temporarily holding a plurality of fabrics upon the table simultaneously, all located above and transversely of the fabrics, knives adjust ably secured to the knifebars above the fabrics, the knives of one bar being inclined in opposite direction to those of the next bar, and means for lifting all the bars and for sliding the knife-bars across the fabrics and then returning them to their -initial position, substantially as described.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

HENRI sIMoNIN.
